Topic: Greetings sound weird...

[ronaldson40]

Hi

Can you help me out with this. I have a wav file created with Audacity at 48Khz and 32 bit float and I want to use this as an IVR greeting. However when I convert wav -> gsm ( 8Khz, 16bit ) using sox,the greeting sounds weird as though  aliens were talking. Can someone help me, with previous experience using sox, to efficiently convert the wav file to gsm.

Regards
Ronald

Just a thought: Why don't you save it in the correct format with Audacity directly?

On my audacity running on macosx, I cannot get the option to export it as a gsm file...

Therefore I need to convert it using sox.exe...

Regards

Ahh, sorry my bad.

Try wavepad (freeware) it can save directly in gsm format.

Hi

I tried wavepad... now I can hear the sound in more audible sense.. but at certain points the speed of the speech keeps varying...

Do you have a zaptel timing source loaded?  If not then you must load ZTdummy to give asterisk a timing source otherwise you can get choppy sound on playback
